Patented Mar. '7, 1922.

Application filed January 10, 1921. Serial No. 436,268.

To all whom it may concern:

Be it known that I, GEORGE CHARLTON VVILDMAN, a subject of the King ofGreat Britain, residing at The Cedars, Riley Crescent, Penn Fields,Volverhampton, Eng land, having invented certain new and usefulImprovements in Engine-Starters, of which the following is aspecification This invention comprises certain improve ments in orrelating to means for facilitating the starting of internal combustionengines. o

According to the present improvements the device is a self-containedunit and comprises a petrol recptaclelocated internally of a hot waterreceptacle, openings being lprovided for pouring in a quantity of petrolinto the petrol receptacle and for pouring a quantity of hot water intothe hot water receptacle when it is required to start up the engine, incombination with means for attaching the device to the induction pipe ofthe engine whereby petrol is drawn into the cylinder or cylinders on thesuction stroke of the engine.

Figure 1 is a sectional elevation of a double tun-dish constructedaccording to this invention.

Figure 2 is a central longitudinal section of a device constructedaccording to this invention, and V Figure 3 is a transverse section online X X of Figure 2 looking in the direction of arrow a.

According to a convenient embodiment of this invention the devicecomprises a cylindrical or other shaped receptacle 1 for receiving hotwater, and a cylindrical or other shaped receptacle 2 enclosed thereinfor receiving petrol. The receptacle 1 comprises a cylindrical wall 3and flanged end plates 4 and 5 which are soldered thereto. Thereceptacle 2 comprises a cylindrical tube which fits in thelsockets 6and 7 on respectively the end plates 4 and 5. The p end plate 4 hasformed thereon a projection 8 and a hole 9 therein registers with holesin the walls of the cylindrical members 2 and 3 to form a petrol inletto the receptacle 2. A hole 10 is formed in the wall 3 to form an inletopening for the hot water. A boss 11 having a hole 12 therein isprovided on the end plate 5, such hole 12 being located at the bottom ofthe receptacle 2 and forming the petrol outlet from the receptacle. Atap or cock 13 is provided with screwed ends 14 and 21, one end havingthe upturned nozzle pipe 15 fitted thereon. The tap or cook 13 isscrewed into a tapped hole into the induction pipe of the engine, the upturned end of the pipe 15 thus passing into the interior of theinduction pipe and being upwardly directed. The bore of the tube 15 issufiiciently'small to spray the petrol, the upturned end not onlydirecting the spray upwardly but also preventing petrol running out ofthe receptacle 2 by force of gravity. This pipe 15 has a tapered end 22for tightly fixing thesame into the tapered end of the bore of the ltap,thus enabling such pipe 15 to be fixed in any "desired -=po'sition inrelation to the tap. The 1 tap 13 is normally retained screwed into theinduction pipe of the engine and to facilitate connecting the starterthereto a union is carried by the boss 11. This union comprises a milleddisc 23 rotatably mounted onthe pipe 24 which is screwed into the boss11. The milled disc is retained on said pipe 24: by means of the collar25 and the screwed bore is adapted to screw onthe end 21 of the tap, awasher 26 ensuring a pctrol tight joint. For the convenience of pouringin the petrol and hot water the double tun-dish 16 is provided, the pipe17 thereon entering the hole 8, whilst the pipe 18 enters the hole 10.An air vent 20 is drilled in the member 5 to allow the petrol to readilyflow into the receptacle 2. A drain cock is fitted to the wall 3 for thepurpose of draining away the water after the device has been used.

When it is desired to start the engine, for instance, in cold 'weatherthe device is screwed on to the tap 13, which as stated is normallyretained screwed in position on the induction pipe. A quantity of petrolis contained in the receptacle 2 and boiling water in the receptacle 1,which thus heats the petrol in the receptacle 2 and causes such etrol toreadily vaporize. The crank shaft is then rotated either by a selfstarter or by the starting handle, when it will be found that the gasdrawn into the cylinder will be fired after the first compressionstroke. The tap 13 need only be opened to allow petrol to be drawn intothe cylinders immediately before starting up, thus providing against thelikelihood of the petrol being drawn away before the time required tostart the engine. The carburetter throttle is preferably closed whilestarting up with the petrol contained in the receptacle 2 so that acharge of petrol may be drawn into the cyl nder, the throttle, however,being then opened im- 'mediately after the engine commences running, andin the case of hand starting the throttle is opened after the charge isdrawn in but before the engine is started. 7

The tap 13 is, in the case of a multiple cylinder engine, fixed to themanifold at a point before it branches off to the several cylinders, Ifdesired fastening means may be incorporated so that the device may beretained .normally'in connection with the induction, pipe.

Claims.

1. A device for facilitating the starting of internal combustion enginesco'mprisinga hot WLliGPl'BCGPtEtClG, a petrol receptacle locatedinternally of the hot water receptacle, a conduit leading from thepetrol container to the induction pipe of the engine, and means forfitting the device to the induction pipe, substantially as set, forth.

- '2. device for facilitating the starting of internal combustionengines comprising a hot Water receptacle, a petrol receptacle locatedinternally of the hot Water receptacle, a conduit leading from thepetrol container, a tap or cock adapted to be fitted to said "conduitand to the induction pipe, and a nozzle pipe fitted to the side of thetapente'ring the induction pipe, substantially as set forth.

3. A device for facilitating the startingof internal combustion enginescomprising a hot Water receptacle, a petrol receptacle l0- cartedinternally of the hot Water receptacle, a conduit leading from thepetrol container, a union carried by such conduit, a tap or cockdetachably screwed to said conduit and screwed into the induction pipe,and a nozzle pipe upturned at one end and tapered at the other end,which. latter end is adjustably fitted to the cock, substantially as setforth.
